Popular sea lion at Long Beach aquarium dies

A popular sea lion, named Odin, at the Long Beach Aquarium of the Pacific has died, officials said Monday.

Odin died Sunday afternoon after a sudden onset of tremors, the aquarium said.

Odin had quickly settled into his new home at the aquarium after he was found stranded and malnourished at Zuma Beach in 2006, according to aquarium officials.

"He was quickly adopted by our other sea lions, who accompanied him around the exhibit for the first time,” Perry Hampton, the aquarium's vice president of animal husbandry, said in a statement. "After that, he could glide around the exhibit on his own."

Officials said Odin had showed no signs of illness or trauma before his death and had been eating well. Further medical investigations were being conducted.
